IMPROVEMENT IN SCHOOL-CHARTS.

Specification forming part of Letters Patent No. 196,348, datedSeptember 18, 1877 application filed June 9, 1877.

To all whom it may concern:

Be it known that I, CYRUS OORNING, of Lawrence, in the county of Douglasand State of Kansas, have invented a new and valuable Improvement inSchool-Charts; and 1 do hereby declare that the following is a full,clear, and exact description of the construction and operation of thesame, reference being had to the annexed drawings, making a part of thisspecification, and to the letters and figures of reference markedthereon.

Figure 1 of the drawings is a representation of a front view of myschool-chart with the covering removed; Fig. 2, a transverse verticalsectional view, and Fig. 3 a front view of the same.

The nature of my invention consists in the construction and arrangementof a schoolchart intended for use in primary and grammar schools, aswill be hereinafter more fully set forth.

The annexed drawing, to which reference is made, fully illustrates myinvention.

A represents a case, of any suitable dimensions, having a horizontalopening, a, centrally across its face. Within this case are arranged twoseries of rollers, B and 0, one series above and the other below thecentral opening a. The journals of these rollers project through oneside of the case and are provided with pulleys b b, as shown. Thesepulleys are connected by cords d din such a manner that the first or toproller of the upper series will be connected with the top roller of thelower series, and so on to the bottom rollers of each series. D Drepresent endless belts passed around the pairs of rollers thusconnected-that is, one belt for each pair of rollers.

In a full-sized chart I propose to have eleven pairs of rollers andeleven belts; but I do not confine myself to any specific number, asthat may be varied to suit circumstances.

On the first belt to the left is affixed, by

printing or otherwise, the words The, An, and A, known as the articlesin grammar. 0n the next belt are, in like manner, affixed a number ofadjectives, and then follow, in rotation, nouns, phrases, auxiliaryverbs, verbs, adverbs, and again the article, adjective, noun, andphrase.

By operating the difierent rollers an indefinite number of sentences canthus be formed applicable both to primary schools and grammar classes.

In the hands of a skillful teacher this chart can almost take the placeof the common school-books.

In the opening a on the face of the case A are fastened strips 'or beadsh h, which form grooves behind them. These admit of slides containing orshowing capital letters, being moved inward to take the place of thearticle on the first place when the teacher desires to have a sentencecommence with some other word.

The beads or strips It It may be made of separate pieces from the faceof the casing A, and fastened thereto, or each may be formed in onepiece with the half-face of the case by beveling the latter on each sideof the central slot, so as to form the beads or strips, as seen in Fig.2 of the drawing.

What I claim as new, and desire to secure by Letters Patent, is

A school-chart consisting of a case, A, with central opening a, havingstrips h, two series of rollers, B 0, connected in pairs, as described,and the endless belts D, all constructed substantially as and for thepurposes set forth.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.

CYRUS GORNING.
